Bosch HSS-Co Metal Twist Drill Bit 8mm x 75mm x 117mm

Summary

The Bosch HSS-Co Twist Drill Bit is an 8mm cobalt-alloy metal drill bit engineered for long-lasting performance in stainless steel and other ferrous metals. Manufactured to DIN 338, it is suited to professional tradespeople and installers who demand precision and durability when pre-drilling anchors, rivets and fixtures. The 5% cobalt alloy content and fully ground HSS construction deliver outstanding wear and heat resistance in demanding applications.

Features

• Constructed from 5% cobalt-alloy high-speed steel (HSS-Co) for superior wear and heat resistance compared to standard HSS bits.
• Fully ground HSS body provides excellent surface quality and consistent dimensional accuracy throughout the bit's life.
• Split-point 135deg tip ensures active cutting and precise centring without wandering, eliminating the need for a centre punch.
• Two cutters and two flutes evacuate chips rapidly, reducing heat build-up and extending bit service life.
• Cylindrical shank (shank diameter equals drill diameter) for secure seating in three-jaw drill chucks.
• Manufactured to DIN 338 Type N (standard flute angle) with diameter tolerance h8.
• Suitable for alloyed and non-alloyed steel, stainless steel (V2A/V4A), cast iron, cast steel, and acid- and heat-resistant steels.
• Designed for use with drill stands, pillar drills and rotary drill drivers; cutting oil is recommended for optimal results.
